BACKGROUND: Angiogenesis is an important characteristic of cancer. Switching from the avascular phase to the vascular phase is a necessary process for tumor growth. Therefore, research in cancer treatment has focused on angiogenesis as a drug target. Despite the widespread use of opioids to treat pain in patients with cancer, little is known about the effect of these drugs on vascular endothelium and angiogenesis. OBJECTIVES: We aimed to investigate the efficacies of morphine, codeine, and tramadol in 3 different concentrations on angiogenesis in hens' eggs...

BACKGROUND: Opioid overdose deaths have become a major public health crisis. While efforts have focused mostly on helping opioid-addicted individuals directly, family members suffer also from the grave and enduring unpredictability associated with opioid addiction and often play a vital role in helping addicted loved ones access care. Little is known, however, about resources to help affected family members. Here we describe results from the first quantitative and qualitative investigation of a free and growing support organization for family members of addicted individuals ("Learn to Cope" [LTC]; www...

This review begins with a comprehensive history of opioid dependence and treatment in the United States. The focus is an evidence-based treatment model for opioid/opiate dependent individuals. The role of reward genetic polymorphisms and the epigenetic modifications that lead to vulnerability to use and misuse of opiates/opioid to treat pain are reviewed. The neurochemical mechanisms of acute opiate withdrawal and opiate/opioid reward mechanisms are explored with a goal of identifying specific treatment targets...

Chronic use of opioid medications has been reported to cause altered sexual function. It is not known if non-opioid pain medications have similar effects. Assessment of this effect through the measurement of concentrations of free hormones is limited. Positivity of opioid medications (hydrocodone, oxycodone, morphine, methadone, tramadol and fentanyl) and non-opioid pain medications (gabapentin or pregabalin) in human serum and plasma samples from adult men and women were evaluated for association with concentrations of free testosterone (fTe) and free estradiol (fE2) measured using equilibrium dialysis-liquid chromatography-tandem mass spectrometry methods...

BACKGROUND: Hyperalgesia or increased sensitivity to pain is often found in alcoholics during alcohol withdrawal and may contribute to relapse drinking. Alternative therapies such as acupuncture and electroacupuncture (EA), through mechanisms involving opioid receptors, may reduce pain and substance dependence and withdrawal syndromes. The lateral habenula (LHb), an epithalamic structure rich in mu opioid receptors (MORs), is a critical target for both drugs of abuse and pain. We previously observed hyperalgesia in rats withdrawn from chronic ethanol (EtOH) drinking and found that EA at the acupoint Zusanli (ST36) reduced EtOH intake...

When immobilising wildlife, adverse side effects can include hypoxaemia, acidosis and hypertension. Pulmonary gas exchange and acid-base status were evaluated during immobilisation of 25 free-ranging and one boma-held black rhinoceros (Diceros bicornis) in Zimbabwe. The effect of different body positions on arterial oxygenation was evaluated. A combination of the following drugs was used: an opioid (etorphine or thiafentanil), azaperone and an a2 -adrenoceptor agonist (detomidine or xylazine). Respiratory and heart rates, rectal temperature and pulse oximetry-derived haemoglobin oxygen saturation were recorded...

PURPOSE: Nasal naloxone is wanted for bystander administration in opioid overdose and as a needle-free alternative for emergency medical personnel. Epidemiologic studies have indicated a therapeutic effect of bystander administration of low-concentration/high-volume formulations. The objective for this study was to describe the nasal pharmacokinetics of a new high-concentration/low-volume nasal formulation of naloxone. METHODS: This was an open, randomized triple crossover trial in healthy, human volunteers (n = 12) where two doses of nasal naloxone (0...

BACKGROUND: Enhanced recovery pathways (ERPs) have been shown to aid in patient recovery and improve outcomes in many surgical settings. At present, there is limited data available regarding the use and feasibility of ERPs for patients undergoing microsurgical breast reconstruction. We sought to assess patient outcomes before and after the introduction of an ERP that was adopted by multiple surgeons at a single cancer center. METHODS: A multidisciplinary ERP was developed for patients undergoing deep inferior epigastric perforator (DIEP) or muscle-sparing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction...

Regulator of G protein signalling 9-2 (RGS9-2) is a striatal enriched signal transduction modulator, known to play a critical role in the development of addiction-related behaviours following exposure to psychostimulants or opioids. RGS9-2 controls the function of several GPCRs, including dopamine and mu opioid (MOR) receptors. We previously showed that RGS9-2 complexes negatively control morphine analgesia, and promote the development of morphine tolerance. In contrast, RGS9-2 positively modulates the actions of other opioid analgesics, such as fentanyl and methadone...

Opioid agonists are used clinically for the treatment of acute and chronic pain, however, their clinical use is limited due to the presence of undesired side effects. Dual agonists, simultaneously targeting mu and kappa opioid receptors, show fewer side effects than that of selective agonists. In the present work, 2D- and 3D- Quantitative Structure Activity Relationship studies were performed on a series of aminomorphinan derivatives as dual agonists, using a wide range of descriptors. The aim of the study was to identify the structural requirements for the activity of these compounds towards mu and kappa opioid receptors and using the models, with best external predictability, for predicting the activities of new hits obtained from shape based virtual screening of drug like compounds from ZINC database...

BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR), a measure of systemic inflammatory response, has been associated with poor outcome in several solid tumors, including prostate cancer. We retrospectively investigated the prognostic role of pretreatment NLR in metastatic castration-resistant prostate cancer (mCRPC) patients treated with first-line docetaxel. METHODS: All CRPC patients treated with first-line docetaxel at two Italian institutions, with available data about baseline neutrophil and lymphocyte values, were included in this retrospective analysis...

The mu-opioid receptor (OPRM1) A118G polymorphism underpins different pain sensitivity and opioid-analgesic outcome with unclear effect on the descending pain modulatory system (DPMS). Primary dysmenorrhea (PDM), the most prevalent gynecological problem with clear painful and pain free conditions, serves as a good clinical model of spontaneous pain. The objective of this imaging genetics study was therefore to explore if differences in functional connectivity (FC) of the DPMS between the OPRM1 A118G polymorphisms could provide a possible explanation for the differences in pain experience...

Osnat Hakimi, Luiz-Claudio Cameron
BACKGROUND: Infertility has been described as a devastating life crisis for couples, and has a particularly severe effect on women, in terms of anxiety and depression. Anovulation accounts for around 30% of female infertility, and while lifestyle factors such as physical activity are known to be important, the relationship between exercise and ovulation is multi-factorial and complex, and to date there are no clear recommendations concerning exercise regimes. OBJECTIVES: The objective of this review was to systematically assess the effect of physical activity on ovulation and to discuss the possible mechanisms by which exercise acts to modulate ovulation in reproductive-age women...

Massive ascites associated with cancerous peritonitis can result in severe respiratory discomfort and abdominal fullness. Additionally, it can significantly impair the activities of daily living of a patient, and relaxation is difficult to achieve, even with opioids. Frequent ascites drainage can cause rapid worsening of the patient's general condition, and a large amount of ascites can lead to discontinuation of anti-cancer treatment. Cell-free and concentrated ascites reinfusion therapy(CART)for refractory ascites was first covered by the insurance system in 1981...

Rijlaarsdam et al. (2016) recently published their findings utilizing a longitudinal design showing that prenatal 'unhealthy diet' was positively associated with IGF2 DNA methylation at birth across both youth cohorts. However, only in the EOP youth was prenatal 'unhealthy diet' positively associated with ADHD symptoms presumably through IGF2 DNA hypermethylation. Rijlaarsdam et al.'s () choice to assess high fat and sugar diet with the Food Frequency Questionnaire (FFQ) may offer some indication as to prenatal nutrient status, as the foods identified by the FFQ in their study are relatively low in free choline...

We studied the possibility of correction of the negative effects of antenatal hypoxia on the liver tissue homeostasis in 7-day-old albino rats by administration of opioid peptides in a dose of 100 μg/kg on postnatal days 2-6. Administration of mixed μ/δ-opioid receptor agonist Dalargin neutralized deviations of gravimetric indicators, parameters of proliferative activity, and activity of the nucleolar apparatus of hepatocytes. Administration of the non-opiate Leu-enkephalin analogue did not normalize gravimetric parameters and nucleolar apparatus parameters, however, it significantly increased the pool of proliferating hepatocytes...
